Does raw domain count matter more than repeat-cited authority? | Trakkr Research
No. The citation graph is broad, but models still repeat a relatively small set of trusted URLs and domains.
Methodology: Built from the live citation index backing Trakkr Research, using 8,777,687 citations across 208,567 unique domains observed between October 3, 2025 and April 17, 2026.
Direct Answer
No. The citation graph is broad, but models still repeat a relatively small set of trusted URLs and domains. Breadth matters for opportunity, while repeat-cited authority is what actually converts into recurring mentions.
What this means
Operators must prioritize building high-trust reference pages rather than spreading content across many low-authority domains, as AI models heavily favor a concentrated set of trusted sources for recurring citations.
